We know it's probably because of the Agincourt because England shouted 'Agincourt!' in episode one. But in my theory is that because England's being such a tsundere. He tries to confess to France, but instead chickens out and starts a fight with France. France, who loves England, wouldn't want to say it because of the past. You know... the episode where France asks England to marry him because his country was in poor conditions. France grew feelings for England, but was afraid England would reject him. While England in the other hand, wouldn't agree on his feelings on France. The reason why they always fight is because, that is the only time they get to be together and stuff. That's why France wanted the fight to go on and also England. THEY ARE IN LOOOOOVVEEEE~~
